KS2 Sats scores... v confused

I've had to speak to my DS's teacher re SATS scores as we are appealing for a place at his preferred school and the appeal panel want scores. The teacher told me that his scores were around 124/5 - i thought they were standardized out of 120 (my older DD went through last year and had a score out of 120) but he said scores went up to 135. Has it changed this year? I'm v confused as school said they have an expected 113 standardized score...

SATs use scaled scores (not standardised) and range is 80 to 120. A score of 135 certainly sounds like a standardised score which is used by a range of assessment schemes so could literally be anything.

He can’t have his SATs results yet as he hasn’t sat his SATs. They are scaled to 120 for all of them and were for last year as that’s what DDs were scaled to last year. Does sound as if it could be CAT scores.
